I have a hen that is laying eggs with some noduoles or protruding rough spots on them. Does anyone know what could be the cause? Here is a picture. Maybe too much calcium? I have been supplementing them with some oyster shells as I have one laying really thin egg shells.
It is just excess calcium. does your feed have enough in it already? If so, you don't necessarily have to make it available unless you notice a problem with soft shells. Since you do have one laying thin shells, I'd keep it available to them and take it away when you stop finding the thin shells if these eggs bug you. Since we've started giving the girls the recycled egg shells (baked to dry and then ground up small) instead of the oyster shell we don't see so many pimples. I think it has to do with the shells having a smaller calcium content, so it's harder for them to overdo it. I could be wrong, it could just be coincidence. Unfortunately, with the geese coming into lay we've burned through our stockpile of shells and had to go buy oyster shell.
